Abdominal contents form midline ridge
Obvious with flexion of neck “lift your head up”
11
Q
Ventral Wall Hernias
When to check for ventral wall hernias?
Technique?
A
- If you suspect but do not see an umbilical or incisional hernia
-
Techniques:
- Ask patient to raise head and shoulders off the table
- Ask patient to raise both legs off the table
- Ask patient to perform Valsalva maneuver
- Bulge of hernia will usually appear with this action
12
Q
Peristalsis & Pulsations
What are they?
Indication if observed?
A
- Peristalsis (visible waves of movement seen beneath the skin)
- Can be seen in very thin people
- Increased peristaltic waves of intestinal obstruction
- Pulsations
- Normal aortic pulsation is frequently visible in epigastrium
- Look for increased pulsation of abdominal aortic aneurysm
13
Q

15
Q
Skin Markings: Dilated Veins
A

- Prominent veins most commonly suggest portal hypertension from cirrhosis
- Portal hypertension promotes collateral venous circulation radiating from the umbilicus to the abdominal wall (Caput medusa)
16
Q
Auscultation
Purpose of auscultation
Why is auscultation performed second?
A
-
Purpose:
- Assess bowel sounds noting frequency and character
- Assess for bruits (atherosclerotic disease)
-
*Second phase of abdominal exam
- Done before percussion or palpation to evaluate the activity of the intestines before altering bowel sounds with abdominal wall pressure
17
Q
Bowel Sounds
- Where do you auscultate for bowel sound?
- What is the frequency of bowel sounds?
- Character of bowel sounds:
- What is normal?
- What is abnormal?
A
- Generally completed in all four quadrants
- Frequency: 5-34 per minute
- Character:
- Active/Normal
- Clicks and gurgles
- Prolonged gurgles of hyperperistalsis, the familiar “stomach growling” referred to as borborygmi
-
Altered/Abnormal
- High-pitched tinkling
- Hyperactive
- Hypoactive
- Active/Normal
18
Q
Bowel Sounds: High-pitched, tinkling bowel sounds
What are they an indication of?
A
Intestinal Obstruction (early): Normal flow of intestinal contents is interrupted. Intestinal fluid and air under tension in a dilated bowel. Multiple etiologies.
19
Q
Bowel Sounds: Hyperactive bowel sounds
Cause?
A
- Diarrhea (gastroenteritis)
- Peritonitis (early)
20
Q
Bowel Sounds: Hypoactive bowel sounds
How to assess?
Indication?
A
- Is it quiet, or is it silent?
- Listen for several minutes
- Ileus – little to no bowel activity (absent)
- Peritonitis – may be hyperactive initially, but eventually becomes hypoactive due to progressively severe inflammation, may progress to an ileus
21
Q
Bruits
Where do you auscultate for bruits?
A
- Aorta
- Renal arteries
- Iliac arteries
- Femoral arteries
22
Q
Percussion
Purpose?
Where do you percuss?
What is normal?
A
- Purpose: Assess distribution of tympany and dullness
- Done in a minimum of four quadrants
-
Normal: Tympany throughout with scattered areas of dullness representing fluid/feces, dullness of liver and spleen
- Tympany – predominates because of gas in GI tract
- Dullness – assess for organ enlargement (hepatomegaly, splenomegaly)
23
Q
Abnormal Percussion
What sounds would you hear? Indication?
Distended abdomen
Protuberrant abdomen
A
- Distended abdomen that is tympanic throughout suggests intestinal obstruction or paralytic ileus
- Protuberant abdomen with bulging flanks and dullness should prompt evaluation for ascites (fluid in peritoneal cavity)
- Free fluid sinks to the dependent part of the abdominal cavity whereas gas-filled loops of bowel float to the top
24
Q
Liver Size
How to measure?
Normal size?
A
-
Lower Liver Border
- Begin in an area of tympany and percuss upward toward the liver
- Note where dullness begins (represents lower liver border)
- Mark with pen
-
Upper Liver Border
- Begin in an area of lung resonance and percuss downward toward the liver
- Note where dullness begins (represents upper liver border)
- Mark with pen
- *Measure the vertical span of the liver in the midclavicular line (MCL), normal size is ~ 6-12 cm in MCL
25

* Hereditary conditions
* Biliary/Cholestatic disease
* Heart failure
26
**Spleen**
When spleen enlarges, which direction(s) does it expand?
How to percuss? What are you percussing for?
* When spleen enlarges, it expands anteriorly, downward, and medially
* Percuss the left lower anterior chest wall from border of cardiac dullness, at the 6th rib, to the anterior axillary down to costal margin and note distribution of tympany to dullness
27
**Bladder**
Is the bladder palpable?
What are you percussing for?
Abnormalities: cause of tenderness or distention
* Usually **non-palpable**
* Percuss for tenderness and fullness in the suprapubic area
* Bladder volume must be \> 400-600 mL before dullness appears
* Abnormalities

* Distention from *urethral stricture, prostatic hyperplasia, neurogenic bladder, etc.*
28
**Palpation**
Purpose
Technique
* _Purpose:_
* Assess for **areas of tenderness**, **muscular resistance**, **superficial masses and organs** (liver, spleen, kidneys), size of aorta
* _Technique:_
* Patient should have **knees flexed** and arms at sides
* Palpate **lightly then deeply**
* Minimum of four quadrants, epigastrium, periumbilicus, and suprapubic
29
**Light vs. Deep Palpation**
* **Light Palpation**
* Elicits abdominal tenderness
* Assess for muscular resistance (guarding and rigidity)
* Identifies superficial masses and organs
* **Deep Palpation**
* Delineates pain
* Identifies masses and organs
* Note their location, size, shape, consistency, tenderness, pulsations, mobility
* Palpate liver and spleen through **respiratory cycle**
* Inspiration moves liver and spleen inferiorly **“take a deep breath”**
* Expiration moves organs back into normal position
30
**Muscular Resistance****:**
_Guarding vs. Rigidity_
* **_Guarding (tensing)_**
* **Voluntary** contraction of the abdominal wall muscles with palpation
* May diminish when patient is distracted
* **_Rigidity (stiffness)_**
* **Involuntary** reflex contraction of the abdominal wall muscles
* Persists over several examinations
31

**Rebound Tenderness**
Purpose
Technique
Positive test
Indication
* _Purpose:_ **Peritoneal irritation (peritoneal sign)**
* _Technique:_
* Press fingers slowly and gently into the abdomen and then quickly withdraw. Observe!
* Ask the patient “Which hurts more, when I press in or let go quickly?”
* Maneuver is positive
* _Positive test:_
* If quick withdrawal of the fingers produces pain

46
**Psoas Sign**
Purpose
Technique
Positive test
Rationale for test
* **Peritoneal irritation (possible appendicitis)**
* _Technique_
* _With patient supine:_ place your hand just above patient’s right knee and ask patient to raise thigh against hand (resisted straight leg raise)
* _With patient lying on left side:_ extend patient’s right leg at the hip
* _Positive Sign_
* Increased RLQ pain with either of these maneuvers
* _Rationale:_
* Appendix lies closely to iliopsoas muscle. If the appendix is inflamed, any maneuver that contracts or stretches the iliopsoas muscle may cause increased pain in the RLQ
47
**Obturator Sign**
Purpose
Technique
Positive test
Rationale for test
* **Peritoneal irritation (possible appendicitis)**
* _Technique:_
* With patient supine, flex patient’s right hip and knee and rotate leg internally at the hip
